Just for reference, I'm not really trying to build the Quartus image right now I'm just trying to figure out the actual FPGA pin usage so I know how to interface it. My experience with Mesa cards is the AIO Eth cards like the 7i76e and 7i96. In those cases the actual pins are already hardware interfaced as in you wind up with a 6 pin differential encoder input, and 4 pin step gen outputs. Without looking at the vhd file, I probably would not have realized that it actually only uses 3 FPGA pins for the encoder and 2 FPGA pins for the stepgens.

I didn't realize the ADC was an SPI interface (had to read the manual again). I thought they were direct connections to the FPGA. That explains why the ADC header doesn't appear as a separate 8 pin section in the vhd file.

Specifically I want to work up an interface board for the DE10 Nano that's more or less specific to my project machine. While I don't really need half of what I want to stuff in there, ultimately a little extra time on the schematic and a couple of chips and resistors is really all that extra functionallity costs. Less specifically I've been working on a machine vision imaging system for some time now. It's kind of a niche thing so it's hard to explain it's actual purpose. This is like one of those probably never ending projects that have any rational reasoning behind it, other than I've had to teach myself quite a few different things every time I decided to do something different. First I built a raggedy "proof of concept" running on LinuxCNC/Mesa. Then I Converted a Small Mill to CNC once again running on LinuxCNC to prototype some more reasonable parts. After designing the whole thing I realized I wasn't super happy with all the bulk of the off the shelf components so I learned KiCAD and started whipping up PCBs. I built a a whole Glade GUI for it and a friend of mine has done all of the custom programming. It currently runs on a reasonably powerful x86 PC that I built to be small and use a DC-DC power supply so I can run the whole machine on a single 24v supply. What happens there is that I wind up needing More CPU than actually necessary because displaying the cameras uses quite a bit of processor and it leads to high jitter on a marginal PC. I've gotten on an ARM kick recently (I've got about 8 SBC's running all sorts of stuff, no Pi's though) and realized that if I can run Machinekit on something like the DE10Nano, I can keep the RT layer off the CPU that is connected to the camera's and there's the added bonus that the FPGA is built right into the same chip as the processor so that hardware becomes very small and low power. On top of that I no longer actually need a fast X86 at all. Image processing, without GPU acceleration spreads out very evenly along CPU cores so these newer 6 core ARM processors handle it pretty well. I picked up an Odroid N2 when it was released so it's not really wel developed under Linux but it still handled it pretty well So yeah there's quite a bit of work to be done to get it running under MK but I figured I'd start by trying to make the DE10 useable as a hardware controller first. https://www.dropbox.com/s/66sjfddnhj5u0mg/Video%20Sep%2007%2C%209%2014%2016%20AM_0.mov?dl=0 https://www.dropbox.com/s/tflf1rtmt8aof5q/remmina_Viewer1%20VNC_192.168.1.108_2019131-14244.932851.jpeg?dl=0 -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
